Seems it is the Video card which has gone bad, If in case your system shows Compaq on your screen, os in that case need to install windows in the system again.But if it does not , Please get your system's Video card again.

connect your laptop to an external monitor using a VGA cable to see if its display. if not, open the PC to check if the memory is properly working, if not, replace it. if the problem continue, check the system processor.

Compaq presario 700 monitor off


Hi
Maybe, depending on the problem. Laptop monitor problems fall into three categories. 1. Screen electronics or lamp. 2. Inverter. 3. Laptop video chip. I've been repairing latops ever since they arrived on the market. First connect an external monitor to the laptop - this will show you whether or not the laptop motherboard is working correctly. If it is then you'll need to replace either the screen or the inverter. So as not to waste alot of money, at this point I would suugest going to a reputable repair person or check my website www.micromendllc.com

Compaq presario 700. The screen, after running for about 5-10 min, gets white lines horiz. and vert. and then goes all white. I have to turn it off for a while and it goes away. (for 5-10 min)


The monitor heat sheild is probably damaged. If you don't have a warranty then you will probably have to replace the lcd panel on the computer.

Hook an external monitor up to it and verify that that screen doesn't scramble. if it does not and the lcd does then the lcd panel is damaged. if both do then you have a motherboard problem with the graphics card. either overheating or damaged. There is also a possibility of memory issues but the first 2 things i mentioned usually over this problem

My computer turns on sometimes the quickly goes blank. Other times, the On light comes on but the screen stays black and nothing seems to be moving inside.


try to desconnect or unplug your hard drive, if you see a black screen with a bunch of white letters, you hard drive is crashed, if not try to conect a second monitor (external) tru you vga connector, if work fine you have a lcd problem===>>>reemplace asap.

Blank screen


I think your LCD is stuffed is it under warranty do you know BUT if the screen is cracked they wont replace it typical HP. To get your external monitor running hold down the function key and the blue monitor looking key similtaneously normally on compaq its the F4 key but look around your keyboard (looks like a monitor) and is blue letters.
